' lllllltours F. norm, or CANANEA, Mnxrcou CINDER-CAR.

To all whom it may concern: I g

Be it known that I, LOUIS F.1(UIIN, a citizen of the United States,residing atCana .nea, Sonora, in the Republic of Mexico, have inventedcertain new and useful Improvements in Cinder-Cars, of which thefollowing .is a. specification, reference being had tothe accompanyingdrawings. y

This invention relates tocindercars used in connection with smelters forreceiving and transporting molten metal and liquid cinder from blastfurnaces and has i for its object to provide a novelsupplemental supportfor the trunnions at eachendof the car,whereby the weight'of the car andcontents is partially taken from the bearing shaft and journal memberfor holding the same. f

Afurther object of thisinvention is to arrange the support ofthisinvention so that it can be readily removed, replacedand inspected,as the conditions require. I "Another object of this inventionis to arrange the sameso that it can be manufacturedand installed at acomparatively low cost, and sothatwhen in position, will not interferewith the tilting action of the car they are placed on.

A still further object of this invention is to provide means whereby theweight will be taken off the sills proper that are used in connectionwith thisclass of cinder cars, so as to relieve the stress from thetrunnions and prevent them bending under'the weight of the bowl of thesame and its contents.

Other objects of this invention will be-,

come apparent as it is more fully set forth.

It is well known that the weight of the bowl and contents of a cindercar strains the bearing shafts that rotatab'ly hold the same, so thatthey are distorted or broken after a comparatively short usage- Ofcourse these shafts could be strengthened by increasing the diameterthereof but such. a

method is objectionable for many obvious reasons. This invention is forthe purpose of relieving the stress entailed in the design of thepresent style of cars used for the purpose, and also in orderto affordmeans of relieving the stress on the bearing shafts and supporting sillsso that they will not be strained in any way by the weights referred to.

At the same time this invention consists in general of a simply formedmember I Specification of Letters Patent. Application filed ()etober 14,1911. Serial No. 654,625.

of the car and under the trunnions of the bowl so that the latter willbe partially supported thereby, and yet not interferein any way withthetilting action of the same. I

In the accompanying drawings which illustrate byway of example anembodiment of this invention, Figure 1 represents aside view of a cindercar embodying this invention,'taken from inside one of the wheels. Fig.2 is a sectional view on the line 22 of Fig. l, and Fig. 3 adetailplanview of I '2 one of the supplemental supports embody-f ing thisinvention. Fig. 4 is a detail show ing the trunnions resting'on thesupporting member.

Similar reference characters refer to simi larparts throughout thedrawings.

r In the construction shown in the draw ings, 1 represents a bowl of.a-cinder car, the opposite ends of which" are provided with trunnlons2, said trunnions being provided with tapered bores 3 which extendpartly f into the same, as can be-ynoted in Fig. 1 of the drawings. Abearing shaft 4: having its innerendportion suitably tapered, is dis:

posed within the bore 8 and provided with a'lock bar 5 which-holds thesame securely in position, suitable registered openings be- 1iOngprovided in the trunnions for said lock ars.

, Suitable journal bearings 6 supporteach ofthe shafts 4 and any usualformoftilting mechanism is mounted upon one of the 1 supports,butforming no part of this in vention and therefore not shown in detail.The journal bearings .6 are carried by the cross bars 7 which extendtransversely. of and are supported by the sills 8. The sills 8 extendbeneath the journal boxes 9 mounted upon the axlelO carried by thewheels 11 of the car and are supported by the hangers 12 connectingsaidsills and journal boxes.

Itwillv thus be seen that the journal bearfings 6 which form the usualsupport for the trunnions transfer their loadto the sills 8 at pointsoutside of the point of support of the wheels by the axles and there isconsequently not only a tendency of the shaft 4 to bend under the loadofthe bowl and its contents but also of'the sills to give at their pointof support by the axle under the bending stress.

The features of construction, thus far described, are of the usual typeand do not constitute any part of the present invention which consistsin the provision of means for relieving the bearing shaft and the sillsof a great portion of the load.

A supplemental support 13 is mounted on the boxes 9 at each end of thecar and has its upper portion 14: bent upwardly and rounded to form anarch as shown in the drawings in order to normaly support the trunnions2.

It will be noticed from Fig. 2 of the drawings that the trunnions 2 aresubstantially oval in cross section so that when the bowl is in avertical position the lower face of the trunnions will rest upon thearched portion of the supports 13 thereby relieving the bearings ofconsiderable weight. WVhen the bowls are turned upon their axis thetrunnions 2 will obviously be out of contact with the arched portion ofthe supports 13 thereby permitting the bowls to be easily turned for thepurpose of emptying their contents.

Suitable holes 16 are provided in the lower and flat portions or feet 15of each arch so that the end portions of the hangers 12 will extendtherethrough and by means of nut-s 17 securely hold the same to theboxes 9. Extending from the curved portion of the member 13 to the outeredges of the same are webs 18 for the purpose of strengthening the same.

Thus it can be seen that the invention while of very simple constructionafiords a means for transmitting a large portion of the weight of thebowls to the journal boxes more directly than is possible by the presentmeans. The general shape of the supporting member in question is such asto permit its ready manufacture and installation and not interfere withthe present existing parts of a car of the nature referred to, so thatthe same can be applied to a car without necessitating any structuralchangein the car.

Obviously while there is shown but one form of this invention in thedrawings, it is not desired to limit this application for patent to thatparticular form, or in any other way otherwise than necessitated by theprior art, as many modifications in the construction thereof may be madewithout departing from the principles thereof.

Having thus described this invention, what is claimed is g 1. In acinder car or the like, the combination, with the wheels, the axles,sills carried by the axles, journal bearings carried by the sills beyondthe wheels, trunnions journaled in the bearings, and a bowl carried bythe trunnions, an arch carried by the axle beneath the trunnions betweenthe bearings and bowl and having an upper convex hearing face to supportthe trunnions intermediate their length.

2. In a cinder car, the combination with the wheels, the axles, sillscarried by the axles, journal bearings carried by the sills beyond'thewheels, of trunnions being elliptical in cross-section and a bowlcarried by the trunnions, a bearing shaft extending from said trunnionsand journaled within the bearings, and an arch carried by the axlebeneath the trunnions between the bearings and the bowl, said trunnionsbeing adapted for rotation whereby when the bowl is in a verticalposition the trunnions will rest upon the said arches and when the bowlis in a tilted position the trunnions will be free of the arches,substantially as described.

3. In a cinder car, the combination, with the wheels, the axles, sillscarried by the axles, journal bearings carried by the sills beyond thewheels, of trunnions being oval in cross-section and a bowl carriedthereby, bearing shafts detachably connected to said trunnions andjournaled within said bearings, a support carried by the axle beneaththe trunnions between the bearings and bowl, the said support comprisingan arched medial portion having, an upper convexed bearing face, saidtrunnions adapted to be supported upon the convex bearing face of thesupports when the bowl is in a vertical position and the said trunnionsbeing free of the said supports when the bowl is in a tilted positionsubstantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
